This is why it is so great that you explain everything so clearly to the customer! I grew up thinking that "drain cleaner", with various brand names, and which had sodium hydroxide as one of the main components, was what we always should use if a plunger doesn't solve the problem. We tried all the amateur methods before calling in a professional plumber. I'm sure the plumbers found the results very annoying. I know better now.

Awwww... I really felt for the lady who said she was going to sleep well that night! This has obviously been weighing heavily on her for a long time! Great work, guys!

I've learned from this channel to use hot water to flush the sink and a little bit of detergent, to ensure nothing gets stuck in the pipes. Thanks!

It depends on what is blocking the drain. If it is hair, skin cells and toothpaste then, NaOH is fine. But NaOH plus fat... that's just going to give you soap. ;) Best thing: DON'T put fat down your drain. Let the fat or oils get hard and cool on your pots and dishes, then wipe it away with paper towels and throw that in the garbage. Not down the drain. My mother used to pour fat and oil into an empty coffee can and keep it under the stove until it was full. Better in a coffee can than blocking the plumbing.

Such polite and grateful customers find you.

I think this video is a great example of how Koreans are benefiting from having a KZfaq channel like Drain Kings to learn about how pipes work. And maybe it will also mean that other plumbers will have to up their game if they aren't providing endoscopy service.

Thanks for another great video Cap, Yang and Choi! I never knew that Sodium Hydroxide could be a bad thing to use in a greasy drain blockage but I'm very happy to have learned that today.

Another happy customer. Good work guys!

Yh always ask the customer if they've used any drain cleaner. That stuff can give you really bad chemical burns if you get it on your skin because you're working with pipework and you don't know it's there. Good unblock and very well explained.

I guess it is just as I have wondered for a while now if potassium hydroxide wouldn't be a better drain cleaner then sodium hydroxide. Sodium hydroxide converts fat into solid soap wich will then block up the pipe. Potassium hydroxide on the other hand generates liquid soap wich will easy flow away instead of blocking up the pipe.

Always glad to watch a new video from my favorite Korean drain cleaning channel.

If they already in malaysia ....they can help a lot of people when their having a trouble with their sewer or drain✨👍❤️ keep it up guys😊✨

Great job guys! Love the explanation of the problem and how you will fix it. 😀🧤🔦

A new Block in the Drain! With the Camera is to see? Sodium Hydroxide. Your clearing the Drain. Good Work. Greeting, 🇦🇹

Some times I think the USA should take lessons from you guys you don't go til it's GONE

Another great video form ye. Love from Ireland 🇮🇪

That's what happens to your heart if you eat too much grease and salt. The arteries get filled, eventually block and you get heart attack. Take care of your drains and your hearts.

1. All blockage in the sink was cleared by the use of Sodium Hydroxide when they got there. Proven when they put the camera in, all was good till they got much further down the sewer to where the original problem was.

5:26 Imagine your arteries from years of McDonalds

So the question still remains...does sodium hydroxide really work on blocked sinks??? 😳

No kidding, I used this stuff to unclog my bathtub, It is really quite nasty, because my bathtub was so clogged that I made a geyser (fascinating view, but it's fumes are really corrosive). Also when I tried to push it with plunger I got nasty burns (I'm fine it was not big deal to me, I got similar burns earlier with a boiling water or oil). So don't try it in home, unless you have a protective wear.

Sodium hydroxide would need high heat to melt fat. Otherwise it could help convert the remaining grease into fatberg’s

Nice job guys!!!

Great job to everyone.

Great work! 😄👍

I thought it was going to be a crazy job

In the cases of a bend to keep water in to hold the smell back, would it best for the owners to make sure they run clean water thru the pipes and make sure to flush as much grease down when they gump the grease?

Great job...nice easy one for you.

Well done 👍

Sodium hydroxide *with bits of aluminum* would generate heat, which could possibly melt the grease.

Good job 👌👌👌

The drain cleaning stuff just made matters worse. That being said there must be a better way to dispose of old oil etc..

where to buy tools they used especially the endoscope

Just dont pour oil down the sink, empty it into old bottles and recycle it or dump it into normal trash so then atleast you save money on plumbers, here they even pay you for the old oil.

I need to buy a flex like that

A friend puked in the shower drain and now it smells horrible. I have tried baking soda, vinegar, hydrogen peroxide, bleach. Please help!

I'm not too late! Let me grab my coffee and biscuits!

Are there any drain cleaner products you do recommend for grease buildup? I think the previous tenant in my place might have been pouring greasy things down the toilet. Ever since winter started I've been having constant drain problems.

You should post more videos😊

if by chance, you have enough money to buy an auger machine, buy one. Auger machine is the best solution for you and your neighbors clogging problem. You can have it rented for return of investment.

i feel sorry for the amount of arguments that happened here and elsewhere bc the sodium hydroxide might have worked in the beginning. and eventually the cameras showed the blindspots that most likely the man of the house never consider until he got humbled. and it is probably why the lady said she can finally sleep well that night. the problems in life are not that easy and do not let a person’s angry ego ruin a respectful and balanced solution with the help of people. no one makes it in life alone. we all can help everyone 👍

So to recycle, i should pour fats and oils down my drain, let it simmer for a year, then had some Lye over time. Let that simmer for about a year, then call a plumber and collect all my free soap?

Not gonna lie, had to look up atherosclerosis cuz I'd never actually heard that word before 😅

Love from India

Do Koreans casually dump oil on drains or just from grease from plates or something that's a lot my friend

flex goes brrrrrrrrrrr

I think it's the same color...the color...or grease. *dun dun*

yuk

Babies usually don't sleep long...

From most of the video, drain/ sink pipe way too small

👍👍👍

Does your service extend to Denmark? 😁

👍👍👍👍

😐

What is it with Asians and putting things in the sink/toilet that don't belong there? Years ago my grandpa had a fourplex and one unit had a big vietnamese family in it. We were called in CONSTANTLY to clear out the sink and toilets because they were always pouring grease and other shit in the sink and toilets. The toilets were the worst; I remember snaking it out once and there were about 1,000 paper towels and non flushable baby wipes, along with food waste like tons of shrimp shells and other nasty shit. No matter how many times we told them not to put that shit in the sink/toilet they kept doing it until we had to kick them out.
